[image error]In honor of Halloween Month, and in the spirit of those SyFy original movies, THE SENTRY is now available in ebook and paperback.

It wakes…

A routine Search and Rescue in the Lacawac Wildlife Management Area leads a group of unsuspecting victims to a terrible truth: Civilization is under siege by an ancient and voracious evil, and it will take every skill they collectively have to survive one night in hell. But is it enough? Because humanity is about to face a war–against the very earth itself.

You’ll never hear it coming until it’s right below you.
